Hoonm) BnoonER STOVE.

Application filed -May 27,

My invention relates to brooders of the general type in which a heater, such as a slow-burningvcoal stove, has its major portion surrounded by a hood or hover which extends to within a relatively short distance from the floor on which the heater seats.

In brooders of this type, it has long been customary to provide the top of the hover with an opening of sufficeint size to permit fuel to be fed into the heaterwithout raising the hover. However, accesslmust also be provided to the base portion of-the stove for removing the ashes from the ash-pit. For this latter purpose, two arrangementshave heretofore been. customary. One, consists in the providing of a rope and pulley arrangement for raising the hover, thereby requiring a considerable addition to the first cost and considerable labor in installing the hoisting equipment. The other consists in making a door or other part of the hover movable, which also adds materially tothe cost and which usually requires the providing of increased rigidity inthe hover parts which remain stationary. Moreover, the movable doors or flaps as provided for this purpose usually afford rather restricted access to the base of the heater, thus making it difficult to clean the floor around the heater.

My present invention aims to provide a brooder in which the hover can readily. be tilted bodily so as to afford free access to the ashpit and to the floor around the heater, while still insuring a rigid supporting of the hover when the latter is in its normal position. It also provides simple means for releasably holding-the hover in its tilted and access-affording position, and provides a heater and hovercombination which will be simple and easy of construction; I

Furthermore, my invention provides a brooder in which the hover is'firmly supported from the top of the heater when the hover in its normal position, in which the hover can readilyvbe rocked with respect to the heater about a predetermined axisv located so that the tilting of the hover will afford ready access to the ash-pit of the heater, and in which the latching means are arranged for ready engagement with the hover when the latter is rocked about the said axis. a I

Moreover, my invention provides a brood er in which simple formations on the hover and theheater co-operate for affording this- 1 927. semi No. 194,582.

rocking or tilting of the hover without requiring auxiliary hinge parts, thereby also permitting the hover to be placed upon or removed from the heater without the use of tools. It also provides an arrangement in which the usual flue pipe-of the heater can serve as a support for a part of the latching means, and in which the hover (when in its normal position) permits a ready opening of a horizontally swinging fuel door. T Y I Stillfurther and also more detailed objects will appear from the following speci fication and from the accompanying drawings, in'which V g I Fig. l is an elevation of a brooder embodying my invention, showing this with the hover in its normal position.

Fig. 2 is a perspective view ofthe same brooder, with. the hover held in its tilted position to affordv access to the ash-pit and the floor adjacent to-theheater. 1 V

Fig. 3 is an enlarged and fragmentary vertical sectionthrough a portion of the hover collar and the adjacent upper parts of the heater, taken along the line 3.3- of Fig. 4. I J I I Fig. 4 is an enlarged plan View of the heater and the canopy top ofthe hover, with portions of the said canopy top broken away. Fig. 5 is an enlarged side elevation-of the upper portion of the heater, with an upper portion of the tilted hover shown in section.

Fig. 6 is a viewisimilar to a portion of Fig. 5,. but withthe hover in its normal or untilted position; r In the drawings, I am showing my invention as applied.to'abrooder heaterof-the type disclosed in. the Gaddis Pate-nt- No. 1,567 ,364; entitled Brooderstove, although I .do n ot'wish to be limited to the employment of my invention in connection with any par ticular type of heater; Inthis Gaddis type of slow-burning coal heater, the heater body 1 is surmounted by a top casting 2 which has an annular lerlge 3 extending laterally AssIGNon ro AMERICAN, STEEL rnonbeyond taller portions of this casting." The top casting 2 is partly cut away to afford a fuel inlet which is normally closed by a horizontally swinging doori, which door is disposed somewhat above the top of the ledge. '3, as shown in.Fig;'3. The top cast ing 2 also has an upwardly directed collar 5 upon whichthe usual flue pipe'G is socketed, and the body of the: stove "as; the usual ash pitrdoor7 near its bottomi as shown in Fig. 5.

The hover of the brooder has as its major portion a downwardly flaring frustro-conical hood which has its upper end larger in diameter than the said ledge 3 of the top casting, this hood being desirably made of radial sheet metal sections 8 secured to each other by bolts 9. The top of the hood composed of these assembled sections underhangs, and is secured by bolts 10 to a downwardly flaring peripheral flange 11 on the canopy top of the hover, which canopy top also includes a top plate 12 connected by a tubular riser portion 13 to the bore of the flange 11. This top plate and the bore of the tubular riser portion are desirably considerably larger in diameter than the upper portion of the heater, and the perforation 13 in the top plate 12 is so disposed as to space the flange 11 considerably from the top of the heater at the side of the heater which is above the ash-pit door 7. The perforation 13 is desirably so shaped that it will approximately fit over the stove top portions which project upwardly beyond the top of the ledge 3, as shown in Fig. 4.

To afford ready access to the. ash-pit, I provide means which. serve as a hinging connection between the heater and the hover, so as to permit the hover to be tilted by rocking it about the top of the heater on an axis parallel to the ash-pit door 7 and at the opposite sideof the heater from that door. This hinging connection is preferably arranged so that its co-acting portions are assembled by merely setting the hover down over the heater, Without requiring the use of any tools. For that purpose, I am here showing the ledge 3 as provided with a pair of circumferentially spaced and upwardly projecting lugs 14, each of which is outward of the main portion of the ledge 3 and each of which lugs extends through a perforation 15 in the top plate 12 of the hover canopy. The lugs 1% have their axes in a plane approximately parallel to the upper edge of the ash-pit door 7 and each perforation 15 is desirably elongated at right angles to the said plane, so as to clear the adjacent lug 14 when the canopy top of the hood is tilted During this tilting, the inner edges of theperforations 15 engage the inner edges of the said lugs, and with the lugs close to the outer edge of the ledge 3 and overhanging the body of the heater, the elongation of each perforation will readily permit the canopy top to be tilted considen ably further than shown in Fig. 5, or to the extent illustrated in Fig. 1.

Then I-provide means for holding the hover in such a tilted, position, as by hinging a hook 16 at its upper end to a strap 17 clamped to the flue pipe 6, and by providing the canopy top with a perforation 18 disposed for receiving the hook end of the in the tubular riser portion 13 as shown in Fig. 3. \Vith the hover thus releasably held in its tilted position, it will be obvious from Fig. 1 that the user has ready access to the ash-pit door 7 for removing the ashes, and that he also is able to sweep the floor entirely around the heater so as to keep this floor in a sanitary condition. As soon as the hook is unsnapped, gravity returns the hover to its normal and axially vertical position of Fig. 1, in which the overlapping of the lee ge 3 by parts of the canopy top plate 12 effectively closes'the top of the hover, so as to afford an upwardly closed brooder chamber around the major portion of the heater.

By constructing my brooder as above described, I can ship the hood sections 3 in a fiat form to reduce the packing space, as the hover can readily be assembled by any one who can handle a; screw driver. Then the mere setting of the hover down on the heater with the perforations 15 slipped over the lugs '14 places the hover inits operative position in which it can instantly be tilted by rocking it upon the heater top edge adjacent to these lugs. During this rocking, the hover is continuously supported by the heater, so that the effort required for tilting the hover is much less than would be needed for bodily lifting a hover in the previously customary manner, thereby enabling even a child to care for a coal-burning brooder stove embodying my invention.

However, while I have heretofore described my invention in an embodiment including a sectional hood, pivoting lugs overhanging an edge of the top casting, and pivoting formationsin the top plate of the hover canopy, I do not wish to be'limited to these or other details of the construction and arrangement thus described, as many changes might obviously be made without departing either from the spirit of my invention or from the appended claims.
